What are the strongest dog shock collars on the market?

Some dogs are relatively easy to train. Those who are lucky enough to have a mellow, eager-to-please pup know and understand that – and yes, we’re jealous of you. 

Other dogs, however, can be incredibly difficult to train. Overly-rambunctious pups might bark, growl, pee where they’re not supposed to, or even bite at times. You may feel like you’ve tried everything; what more can you do?

Dog shock collars serve as excellent training tools that can make it increasingly apparent that their bad behavior will elicit an unpleasant punishment – i.e., a shock. 

Today, we’re here to talk about shock collars: what they are, how they work, and which are the best. Our reviews of the strongest dog shock collars can help you decide which is the best option for your disobedient dog. 

In a hurry? These are our top 3 strong dog shock collar picks

What is a Dog Shock Collar?

A dog shock collar is exactly what it sounds like. It’s a training device in the form of a collar that features a receiver linked to a remote control. The receiver usually has two protruding metal points that sit against your dog’s skin on their neck. 

Meanwhile, you can control the collar via the remote control. When your dog exhibits bad behavior, you can discourage it by sending them a quick shock as a response, followed by a strong command and scolding. 

Many dog shock collars feature three settings:

  • Beep
  • Vibration
  • Shock

These settings are designed to give you a way to increase your dog’s punishment gradually. Eventually, features such as the beep or vibration can even serve as a warning sign of what’s coming if your dog refuses to listen: the shock.

Additionally, shock collars usually have several levels of shock intensity. For some dogs, it only takes a small zap to get their attention and get them back on track. Other more stubborn, difficult dogs might require a stronger shock.

How to Properly Use a Shock Collar

A dog shock collar can be an incredible training tool to transform your dog’s bad behavior when used properly. 

However, far too often, people use shock collars irresponsibly. The shock collar can quickly turn into a destructive, unfair, and even cruel punishment rather than a training tool. 

Because we love our dogs – and all dogs, for that matter – we’re going to give you a few essential tips to review before diving into our products.

Start With Traditional Training

Before you even touch a shock collar, you must attempt to train your dog with traditional training methods. If your dog doesn’t have some kind of baseline, he doesn’t stand a chance against the threat of a zap. 

Maybe your dog doesn’t entirely listen all the time, but if you can instill a few commands using treats and positive reinforcement, you’ll have a much better time when you use the shock collar. 

A few good basics to work on include common commands like come, sit, and stay.

Allow Your Dog to Get Used to the Collar

Shock collars are often heavier and bulkier than standard collars, so they’re going to feel different on your dog. You won’t have any luck training them if they’re distracted or uncomfortable, so be sure to give your dog time to get used to the new collar.

Combine Training Techniques

Shock collars basically only focus on negative response training, but what your dog really wants to do is please you. Using only negative responses, such as vibrations or shocks, isn’t the ideal way to train. 

Many people use a combination of negative responses with positive reinforcement. For instance, when your dog doesn’t listen, he gets a buzz. When he does listen, he gets a treat. These far opposite responses make the good and bad decisions very obvious.

You also want your dog to be able to listen to you without the collar. If the only training tool you use is a shock collar, it’s not likely that your dog will listen when he’s not wearing it. 

Use the Lowest Intensity Possible

As dog people, we firmly believe that the crime should fit the punishment. And while shock collars are incredibly safe, that doesn’t mean you should be using the highest setting possible.

That being said, you should always use the lowest setting possible. 

Most shock collars also have a beep and a vibrate setting. Start with the beep setting and see how your dog reacts to that. If your dog ignores the beep, try using the vibrate setting. If he ignores that, go for the lowest shock level – and so on. 

Remember that the goal here is not to hurt your dog, but rather use the unpleasant feeling of a minor shock to correct his bad behavior.

Final Thoughts

Dog shock collars tend to be quite controversial, but that’s typical of people who don’t know how they work or what their purpose is. 

Dog collars were never meant to harm a dog. In fact, they’re exceedingly safe. The stimulation that comes from modern-day training collars is not painful, but merely a “shock” to your dog to help train them.

We’ve offered you three different options today – all of which come with our personal blessing. Choose the one that best suits the needs of both you and your dog.
